GNSS Positioning

Status and Features
Nowadays, GNSS receivers have scores – and often hundreds – of channels, enabling them to track GPS, Glonass, Galileo and Compass signals simultaneously. The whole workflow from satellite tracking to calculating the coordinates of the position in a preferred reference system can be conducted automatically in real time. The price of GNSS receivers has dropped steadily since the first GPS receivers came onto the commercial market in 1982. In conjunction with the latest product survey results for GNSS receivers (available at www.geo‑matching.com), the author puts today’s GNSS status and features in perspective.

Hemisphere GNSS Releases New GNSS RTK Engine

Hemisphere GNSS has announced the launch of Athena, its next-generation GNSS engine. According to the company, the new core engine has been designed to maximise the ability to excel at the rigorous GNSS requirements of multiple market segment customers in machine control, survey and GIS. Athena is developed for application in virtually every environment where high-accuracy GNSS receivers can be used. Hemisphere’s customers have tested and proven Athena’s performance in long baseline, in open-sky environments, under heavy canopy, and in geographic locations experiencing significant scintillation. The company claims the brand-new GNSS RTK engine has one of the most reliably consistent... (read more)

GNSS and Heavy Equipment

Financial Benefits of Telematics and Machine Control
Heavy equipment represents a major capital cost for companies in industries such as construction and agriculture. In recent years Global Navigation Satellite System (GNSS) technology, which uses signals from US Global Positioning System and the Russian Glonass satellite system constellations, has been used to improve fleet efficiency. Many companies may hesitate to invest in the technology because management is unaware of its benefits. Such hesitation has only increased during the current global economic downturn. However, recent evidence has emerged to demonstrate the measurable impact GNSS technology may have on company profits.   Equipment telematics, the wireless exchange of electronic information...

Leica GPS1200+ GNSS

Four independent Global Navigation Satellite Systems (GNSS) will be operational within the near future. With the new Leica GPS1200+ users can be certain that they are ready. The Leica GPS1200+ supports the new GPS L5 signal, GLONASS L1 and L2, and will also be able to track Galileo and Compass satellites when available. The flexible design of Leica GPS1200+ is 100% future proof and is already now compatible with the four global navigation satellite systems.     GPS L5 is the new third GPS frequency which will allow increased redundancy, faster signal acquisition, and improved multipath performance - ultimately resulting...

GNSS Rapidly Gains Ground

Enhancing the Speed and Quality of Pipeline Construction
GNSS, short for Global Navigation Satellite System, is rapidly gaining ground as a tool in many different areas of work. Dutch contractor A.Hak is one of the companies at the forefront in terms of incorporating this technology's many applications into its everyday operations. A prime example of a project in which A.Hak has embraced GNSS is the construction of the North-South Route, a major gas pipeline that will run from the province of Groningen in the north to the province of Limburg in the south of The Netherlands. It is a project that involves a lot of precision digging.  ... (read more)

Four times GNSS

A Worldwide Race
The Munich Satellite Navigation Summit opened during the first week in March 2009 with a plenary session entitled ‘The Worldwide Race in GNSS’ and closed with a panel discussion on the subject of ‘competition among the Big Four’. Although several speakers did their best to convince attendees that there was no race or competition, it is obvious that four systems serving the same market will be involved in a race for the best technical solutions and engage in fierce competition. If it is indeed a race/competition, let us have a look at the score so far. GPS Since 1978 this... (read more)
